📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise including sensitive employee data, attendance records, and potential credential theft leading to further system access.

🟠

Likely Case

Data exfiltration of sensitive employee information and attendance records, potentially leading to privacy violations and operational disruption.

🟢

If Mitigated

Limited impact if proper network segmentation, WAF rules, and input validation are in place to block SQL injection attempts.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

SQL injection vulnerabilities are commonly exploited and this requires no authentication, making exploitation trivial for attackers.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 3.1.053 or later

Vendor Advisory: https://www.themissinglink.com.au/security-advisories/cve-2023-26581

Restart Required: Yes

Instructions:

1. Download latest version from IDAttend vendor portal. 2. Backup current installation and database. 3. Install updated version. 4. Restart application services. 5. Verify functionality.

🔧 Temporary Workarounds

Web Application Firewall Rules

all

Implement WAF rules to block SQL injection patterns targeting the GetVisitors endpoint

Network Segmentation

all

Restrict access to IDWeb application to internal networks only

🧯 If You Can't Patch

  • Implement strict input validation and parameterized queries for the GetVisitors method
  • Deploy network-level controls to restrict access to the vulnerable endpoint

🔍 How to Verify

Check if Vulnerable:

Check IDWeb application version in admin interface or configuration files

Check Version:

Check application web interface or consult configuration files for version information

Verify Fix Applied:

Verify version is 3.1.053 or later and test GetVisitors endpoint with SQL injection test payloads

📡 Detection & Monitoring

Log Indicators:

  • Unusual database queries from web application logs
  • Multiple failed SQL syntax attempts
  • Unexpected data extraction patterns

Network Indicators:

  • SQL injection patterns in HTTP requests to GetVisitors endpoint
  • Unusual database connection spikes

SIEM Query:

source="web_logs" AND (uri="*GetVisitors*" AND (payload="*' OR *" OR payload="*;--*" OR payload="*UNION*"))
